I bought a usb card reader, does it store files like songs and word documents, if so how do i save them to it? I plug it in and nothing comes up or anything. 10 points!:)
No it just reads, the card reader alone cannot store files.
It can't store anything. You can put memory cards[1] in it, and it can read and write data to and from them (then THEY can store the data (any kind of data, a computer file is just a computer file, it doesn't matter what is in it)). [1] compact flash, SD, and various others, which ones are supported depends on the particular card reader
